It should work. Do you have any sample files? Then I can check if there need to be special handling.

Here is what I get with the OpenVDB Node. I had to flip the axis but the file seems to be imported correctly for me.

Yes, I have to simplify the node and add some internal checks to make the node more fail proof then it can be added to the master branch.

Any news about the current state of openvdb? I have a perfect case where I could utilize this feature :D

The code was merged into master yesterday. Please feel free to test it. There still are some issues with animated external files, e.g. houdini, which I cannot test due to lack of example files.

Thanks a bunch. I'll start testing with a vbd sequence from Houdini, I am curious to see how it turns out

So far I have been able to render Houdini sim without any hiccups. Only problem I am facing is matching the location and size of the volume to how it was in Houdini. I guess I should match the smoke domain used in Blender to the one that was used for simulating in Houdini?
